DIRIGIBLE HEADLIGHT.

Application led December 4, 1926. kSerial No. 152,643.

providev novel and improved means forY maintaining the headlights in substantial alignment with the front wheels of the vehicle.

A; still further object of the invention is the provision of a structure such that the vertical angle of the beam of the headlight with respect to the horizontal `may be readily adjusted.

These and other objects 1 attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a front elevation of a` vehicle having dirigible headlight mechanism'and control elements therefory constructed in accordance with my invention;

liiigure 2 is a plan view of the control mechanism, a portion of the headlight mounting being shown in section;

Figure 3 is a `vertical sectional view through the headlight mounting;

Figure et is a fragmentary side elevation of the headlight mounting showingl the means for adjusting the angle of the head light;

Figure 5 is a fragmentary sectional view through the headlight mounting at the lower end thereof showing the disposition of the control aud connecting arms; i

Figure 6 is a fragmentary view similar to that shown in Figure 2 and illustrating a modified control mechanism; j

Figure 7 isA a similar view illustrating a still further modification of the control mechanism; Y j

taken through the front section of the auto mobile showing a still further modification of control mechanism.

Referring now more particularly to the drawings, the numeral 10 generally designates suitable brackets adapted to be attached to the fenders 11 of a vehicle and formed at their outer ends with split collars 12 which may be restricted by clamping 'screws 13. Adjacenttaces ofthe collars are preferably braced to one another by a transversely extending brace 14.

Mounted within the collars are vertically extending tubular easings 15 which are each provided interiorly adjacent their lower ends withl a flange 16 providing a sea-ttor a' bearing 17 through which is directed a shaft 18. `Above the flange 16 in spacedrelation thereto, each'c-asing is provided with an interior shoulder 19forming a seat for the thrust bearing 20. The shaft 18 is provided with anienlargement 21,` Ythe lower end, of which seats upon the upper member of `the thrust bearing to limit downward movement of the shaft therethrough. Below the bearing 17, the' shaft 18 is'threaded at 22 and has adjusting and loclrnuts 23 and 241 Amounted thereon.' The lower end of this yshaft has secured thereto an arm 25 operating withina notch 26 formed in the casing.

` Mounted within and held against rotation with relation to the casing immediately above the thrust bearing 20 is an insulating ring 27 having in its uppper surface an annular ring contact 28 from which a lead 29 extends throughandis insulatedfrom the wall of the casing.` This lead may be connected with the lead wire 30 controlling the headlight. Secured to and held against rotation with relation to the shaft 18 and seatn ing at its lower end upon the enlargement 21 is a second insulating ring Blliaving mounted therein a spiingpressed brush 32 for engagement with rthe annular ring contact 28.

Secured to the upper end of theshaft 18, by a set-screw is a cap 34, the lower face of which has an annular `groove 35 within which the upper end of thewall of the tubular casing 15 extends. A sleeve 38 surround ing the shaft 15 between the upper surface of the insulating ring 81 andthe cap 34 limits downward movement of the cap and insures against binding engagement between the upper -wa-ll of this groove and the upper f j `face ofthe side wall of the casing. Figure 8 is a horizontal sectional view i" The cap 34e has uponits uppersurface an apertured ear 37 adapted to extend between corresponding ears 38 formed upon a headlight bracket 39 to which the headlight 40 is directly secured. A pin 41 connects the ears for rotation. bracket 39, the ear 37, cap 34, pin 41 and the upper end of the shaft 15, a bore 42 is formed for the passage of a lead wire for controlling the illuminating element of the headlight.

Through the base of the The bore, atitsloircr end, liaslaii angular portion extending through the 'sleeve 36, so

Vthat the lead Wire nia-y be electricalljT connected with the brush 32 to complete the circuit. Threaded inthe capBeL, at opposite sides ot the pivotal center ot the bracket 39, are a pair of adjnstiifigir screws 43, the heads ot which are adapted t abut against the bracket 39 through lugs let and provide a .f means whereby thehorizontal anpgle of the bracket Aund accordingly the angle "of the beam of the headlight, with respectto `the horizontal, niaybe adjusted. I/Vhere` a` pair ot headlights are provided with mountings ot this character,theshatts are preferably link-connected,with .one another as, tor cx- "ainpleybjf u bnr to maintain ithe headlight brackets in desired relation with one another. Itwillbe obvious that awlieadlight mount ing ol this charalcter may 'berery readily` rotated and that' accordin`,`ejly` a `"very light upon its lower enduvith an operating arm 46 at prcsentshown as formed integrally with and'projecting reaiurardlji` from thearni 25 to which.. one end of a Bowden Wire eti' is adjustably connected.

The `opposite end o'lltlie Bowden'wire 47 is operatively secured to the steering arin`52nt apoint spacediroin thepivotal center-there- H `sliait and engine-ingr thelowcr end ofthe oh In this tigurejan extension bracket is attached directly tothe steerii'ig arm. l

In Figure 6, the structure above recited is reintorcedby a substantially duplicate structure including` additional clumps 48* upon theiender bracket und` 5l11 upon theaxle.

Inetend of employing the arm 46, a cross arni 16a V.is provided, to one end o't which the wire il? is adjustably connected. AA second wire all is connected to the opposite end nl' l thecross arm at one end andi at its opposite end is directly connected to the steering` arm r j o2. j i

, In the form shown iirFigure 7, the structure is again varied from 4thatfsliown in the j figure last(discussed-by` providingr the king The A adj ucent tender l bracketlO'is provided `with a clamp 48 securing;r onel endot the BoWdenWii-e housingf or dexililctubingt), while the uxle 50 ofthe boltfl ot the steering lirinwitliu T head to which thellowden wircsly connected. This figure also llluetrates the tact that adjustment ot' these Bowden wires as to effective length ii'iay he niadc nt either end of thewire, the adjustment in the present instance being at that end ol the wires which nrc secured to `the "l" heini. p

In Figure 8, a` further variation of the structure shown in Figure l is disclosed. I--lere the structure oit this latter ligure is duplicated at opjiosite ends oi. the eide and upon the tender brackets at ilpposite sides oit the vehicle, with the exception o'l the tact that `the upper end o't the king' hols 54- orc provided wi th :angular extensions 5G to which iliewires are conne(A ed. These wires are,in duct, .ippoeto ende` ol a" single wire,"which,

"in this etructurc, will provideuronnection 5T between the lump Willits, insuring their movement in unison' and replacing tliebar 45.

`It will be ohvoious that the construction hereiiibefore set forth "is capable of: u certain range oi. change `and `inoditicution `without materially departing;` troni the spirit ol the invention and I accordingly do not linut nirsellg to such specific structure except ne hereai'ter claimed. 1 i
